WRENCH.

SPECIFICATION forming part of Letters Patent No. 478,121, dated July 5,1892.

Application filed March 3, 1892.

To all whom it may concern:

Be it known that we, WILLIAM MILLER, of Hillsdale, Ilillsdale' county,Michigan, and WILLIAM S. DUVALL, of Washington, District of Columbia,citizens of the United States,

have invented a new and useful Wrench, of

which the following is a specification.

This invention relates to improvements in rod and pipe wrenches, theobjects in View being to provide a wrench of great simplicity anddurability, that may be readily applied and as readily grip rods andpipes located in various positions and willaccommodate itself to rodsand pipes of various sizes.

A further object of the invention is to adapt the wrench to serve as awire or rod cutter, and, furthermore, to adapt the same to operate uponperforated glands as employed in packing-boxes for pistons and otherrods.

Vith these objects in view the invention consists in certain features ofconstruction hereinafter specified, and particularly pointed out in theclaims.

Referring to the drawings, Figure 1 is a per spective of a wrenchconstructed in accordance with our invention. Fig. 2 is a plan viewillustrating the manner of applying the same to a gland. Fig. 3 is anelevation illustrating the manner of employing the wrench as awire-cutter.

Like numerals of reference indicate like parts in all the figures of thedrawings.

The wrench-stock 1 has its outer end curved, as shown, to form thestationary jaw 2, the same being provided with a series of teeth 3,disposed toward its extremity and formed transversely upon its outer orconvex face. The inner edge of the jaw is curved or quad- {ant-shaped,and preferably terminates in a 5 designates the curved movable orpivoted jaw, the same having its inner face provided with a series oftransverse teeth 6, oppositely disposed to the teeth 3 01 the jaw 2 andadapted to coact therewith in gripping a pipe, rod, or other cylindricalobject. In rear of the jaw 5 its shank is split or divided, formingbifurcations. These bifurcations are spread apart,

as shown, to receive the stock 1. The bifur- Serial No. 423.620. (Nomodel.)

cation 7 is continued some distance beyond the bifurcation 8, and apivot pin or bolt 9 passes transversely through the two bifurcations andthe stock. That corner of the bifurcation -7 of the shank which contactswith the adjacent corner of the stock 1 is made perfectly square to forma sharp cutting-edge 10, and a similar cutting-edge 11 is formed on thesaid adjacent corner of the stock.

In operation as a wrench for rods, pipes, &c., it is simply necessary toengage the jaw 5 under or over a rod or pipe and swing the stock 1toward an alignment with said jaw, causing the stationary jaw 2 to biteor bind upon the pipe. A continued motion of the stock 1 carries with itthe rod or pipe, and

thus the same is manipulated.

In Fig. 2 we have illustrated how the device may be employed forremoving glandnuts. In the said figure, 12 designates the gland-nut,provided, as is usual, with peripheral countersunk cavities 13. The twojaws of the wrench are closedthat is, the terminals 7 and 8 liealongside of the stock 1and the lug 4 is applied in any one of thecavities 13 of the aforesaid gland-nut. Now by pressing the inner edgeof the curved jaw 2 closely against the periphery of the nut andoperating the stock 1 the nut may be either applied or removed, afterthe ordinary manner of accomplishing the same, through the well-knowngland-nut wrenches made especially for this purpose.

In Fig. 3 we have illustrated how the device may be employed as awire-cutter, and in such instance it is preferable to rest the movablejaw 5 upon abench or other support .and lower the stock 1 at its innerend, so that the long terminal 7 and the stock separate. A wire beinginserted between the separated stock and terminal 7, it is onlynecessary in order to sever said wire to raise the inner end of thestock in an attempt to bring the two jaws together, so that the edges 10and 11 are forced by each other andact to sever or cut the wire, whichwe have indicated in position therein. From this description it will beseen that we have provided a wrench for pipes and rods of cheap andsimple and du- Having described our invention, what we claim is 1.

edge and its outer end curved to form a stationary jaw having an innereoncaved and outer convexed face, the latter provided with teeth, saidjaw at its outer extremity and concaved side being reduced to form aeylindrical lug adapted to engage the perforationsin a gland-nut, of acurved jaw having its shank bifurcated and spread to embrace the stock,and pivoted thereto in rear of its bent end, one of said bifurcationsbeing extended be yond the pivot some distance to form awirecutter andhaving one of its corners squared and adapted to coact with the squaredeutting-corner of the stock, substantially as specified.

In testimony that we claim the foregoing as our own we have heretoaflixed our signatures in the presence of witnesses.
